Glossy black fuel
Anthracite is the hardest, most carbon-rich form of coal, prized for burning hot and clean with little smoke.
It has a shiny, almost metallic black luster that distinguishes it from softer coals: anthracite mining in Pennsylvania.
The adjective describes this coal or its deep black color.
